Strawberry plant named ‘FPS-14_552-008’

ABSTRACT

This invention relates to a new and distinct variety of strawberry plant named ‘FPS-14_552-008’. This new strawberry plant named ‘FPS-14_552-008’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its red fruit color, medium fruit size, and conical fruit shape; excellent fruit flavor, medium skin firmness, with seeds typically held even with the surface; very smooth fruit surface, even in color, with a slight difference in size between primary and secondary fruit; medium to large plant size, upright in habit with medium density; medium yellow green foliage color, and medium to large foliage size; and fruiting trusses typically held level with to below the plant, with medium to high pubescence.

Latin name of the genus and species of the plant claimed: Fragaria x ananassa.

Variety denomination: ‘FPS-14_552-008’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘FPS-14_552-008’. This new variety is a result of a controlled cross made in 2014 in an ongoing breeding program between strawberry variety designated ‘Sonata’ as the seed (female) parent, and strawberry variety designated ‘BG-4315’ (U.S. Plant Pat. No. 23,257) as the pollen (male) parent. The variety is botanically known as Fragaria x ananassa.

The seedling resulting from the aforementioned cross was selected from a controlled breeding plot in Santa Cruz County, Calif. in the spring of 2016. After its selection, the new variety was asexually propagated by stolons in San Joaquin County, Calif. The new variety was tested extensively over the next several years in fruiting fields in Santa Cruz County, Calif. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true-to-type through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘FPS-14_552-008’ is primarily adapted to the climate and growing conditions of the central coast of California. The nearby Pacific Ocean provides the humidity and moderate temperatures needed to produce a strong, vigorous plant and maintain fruit quality during the April through June production months.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘FPS-14_552-008’, which in combination distinguish this strawberry plant as a new and distinct variety:

-   -   1. Fruit is red in color, medium in size, and conical in shape;     -   2. Fruit has excellent flavor, medium skin firmness, with seeds         typically held even with the surface;     -   3. Fruit surface is very smooth, even in color, with a slight         difference in size between primary and secondary fruit;     -   4. Plant is medium to large in size, upright in habit with         medium density;     -   5. Foliage is medium yellow green in color and medium to large         in size; and     -   6. Fruiting trusses are typically held level with to below the         plant, with medium to high pubescence.

The strawberry variety that is believed to be most closely related to the new variety ‘FPS-14_552-008’ is ‘BG-4315’ (U.S. Plant Pat. No. 23,257). In side-by-side comparisons to the similar strawberry variety ‘BG-4315’, ‘FPS-14_552-008’ differs by the following combination of characteristics as described in Table 1.

TABLE 1 ‘BG-4315’ (U.S. ‘FPS-14_552- Plant Pat. Characteristic 008’ No. 23,257) Fruit: color Red Orange red Fruit: Season average size (grams) 21.0 26.9 Terminal leaflet: shape of base Obtuse Acute Terminal leaflet: margins (shape Obtuse (serrate Rounded of teeth) to crenate) (crenate) Foliage: interveinal blistering Medium to strong Absent or weak Petiole: Size (cm) 20.2 15.8 Plant: spread (cm) 37.1 (large) 25.2 (small) Fruit: Flavor Excellent Fair to good Flower: sepal color Yellow green Green group (upper surface) group (144B) (137B)

For identification, a series of molecular markers have been determined for this new variety.

‘FPS-14_552-008’ differs from its parents, ‘Sonata’ and ‘BG-4315’ (U.S. Plant Pat. No. 23,257) by the following combination of characteristics as described in Tables 2 and 3.

TABLE 2 Characteristic ‘FPS-14_552-008’ ‘Sonata’ Fruit: color Red Orange red Fruit: size Medium to large Small to medium Fruit: flavor Excellent Fair Plant: size Large Medium

TABLE 3 ‘BG-4315’ (U.S. Plant Characteristic ‘FPS-14_552-008’ Pat. No. 23,257) Plant: type June bearer Short day Fruit: firmness of flesh Medium Firm Fruit: flavor Excellent Fair Plant: size Large Small to medium

DETAILED BOTANICAL DESCRIPTION

The new variety ‘FPS-14_552-008’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘FPS-14_552-008’ may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location. In addition, the characteristics of any parental variety or comparison variety included in Tables 1, 2 and 3 of the present invention may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.

The aforementioned photographs, together with the following description of the new variety ‘FPS-14_552-008’, unless otherwise noted, are based on observations taken during the 2022 growing season in Santa Cruz County, Calif. These measurements and ratings were taken from plants of ‘FPS-14_552-008’ dug from a low-elevation nursery located in San Joaquin County, Calif. in December 2021 and planted approximately two months later in Santa Cruz County, Calif. The approximate age of the observed plants is three to four months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, are averaged from five years of data collected from the 2018 through 2022 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit, unless otherwise noted.

Where noted, color terminology follows The Royal Horticultural Society Colour Chart, London, Sixth Edition (2015).
